  • Patent number: 8292698
    Abstract: An on-line method of cleaning contaminants from at least one interior surface in plasma chambers comprises blasting one or more interior surfaces of a plasma chamber with dry ice to remove contaminants from the one or more surfaces.
    Type: Grant
    Filed: March 30, 2007
    Date of Patent: October 23, 2012
    Assignee: Lam Research Corporation
    Inventors: Hong Shih, Oana M. Leonte, John E. Daugherty, Tuochuan Huang, Gregory J. Goldspring, Michael C. May
  • Patent number: 6524657
    Abstract: Aromatic aliphatic ether solvents, such as anisole, methylanisole, and phenetole, have been found useful in formulating coating solutions of polymeric dielectric materials and as a clean up solvent in the coating process. A process for forming a dielectric film on a substrate includes depositing a coating solution of a dielectric material in a formulation solvent onto a surface of the substrate and depositing an aromatic aliphatic ether solvent onto an edge portion of the surface of the substrate. The process is used to form films of dielectric materials including arylene ether dielectric polymers, hydridosiloxane resins, organohydridosiloxane resins, spin-on-glass materials, partially hydrolyzed and partially condensed alkoxysilane compositions which are cured to form a nanoporous dielectric silica material, and poly(perhydrido)silazanes.
    Type: Grant

  • Patent number: 6348119
    Abstract: A method, a system and a product made therefrom including the steps of providing electrically non-conductive pieces or fragments, causing at least a portion of the electrically non-conductive pieces or fragments to become temporarily electrically conductive, combining adhesive which sets when sufficient heat is applied thereto with the temporarily electrically conductive pieces or fragments, and applying voltage across the temporarily electrically conductive pieces or fragments and adhesive combination so as to produce an electric current through the temporarily electrically conductive pieces or fragments which, in turn, generates heat within the temporarily electrically conductive pieces or fragments and adhesive combination.
